My husband has flail arm MND. It started with fasciculations in his arms and then his right arm lost strength - he was struggling to lift it etc and then in December 2016 he was carrying 2 drinks at a party and nearly dropped one as his right arm wasn't working properly. It gradually got worse, his neurologist tried a couple of treatments for various possible diseases but none worked. He had to stop work and driving in June 2017 (was a bricklayer) and got diagnosed in October 2017 at the National Neurology Hospital in Queens Square. He gradually gets worse and now he is virtually paralysed. Apparently flail arm can have a slower disease progress than other versions of MND. His MND specialist said that this is not always the case and I suspect he knew Tony was a faster progression. Hopefully your progress will be slower. We have lots of input from occupational therapy, physios, speech and language etc and they all make things easier. Take care
